The Maxima 5.14.0 value agrees with the mma function evaluattor; see
http://functions.wolfram.com/webMathematica/FunctionEvaluation.jsp?name=Zeta2
Specifically,
(%i17) fpprec : 50$
(%i18) mma : 12.103813495683755105709077412966680619033648618088b0;
(%o18) 1.2103813495683755105709077412966680619033648618088b1
(%i19) maxima : bfhzeta(1.1b0,1/2,50);
(%o19) 1.2103813495683755105709077412966680619033648618088b1
(%i20) mma - maxima;
(%o20) 2.138211768073756516912429173721185503052157504084b-49
Changing 1.1b0 to 1.1, we have:
(%i21) maxima : bfhzeta(1.1,1/2,50);
(%o21) 1.210381349568374531600056798197329044342041015625b1
(%i22) mma - maxima;
(%o22) 9.7897085094309933901756132384618379886877317467267b-15
OK fine --- you need to be careful about such things.
